Question about 1984 Volvo 240 Series

3 Answers

Brake problems We have a problem with our 1984 240 GL Volvo. The brake pedal went to the floor while driving, after pumping it the pedal came back. I took it to the shop and they said I needed a master cylinder. They put a new master cylinder in and when I drove it away from the shop the brakes began making a horrible noise and felt like they were dragging badly, something clearly was not right, I took it back to the shop and they pulled the front wheels off and told me I needed brake pads but they could not do them that day. So I drove home. We put on pads, calipers, rotors, and all new brake lines. We bled the entire system but we have no pedal at all, it goes all the way to the floor. What could the problem be?

I had a somewhat similar problem, brake failure. Had them bled 3 times by the same place (a Mavis dealer - it was the closest place to me). Turns out the cause was that (and I honestly forget which brands have how many bleeder valves in the front), but I read that one brand has 3 or 4 valves, another only has 2. The idiots at Mavis were only bleeding 2 out of the 3 (or was it 4?) valves - as they were only used to the one brand... When I brought it to a small repair shop that specializes in Volvos they ID'd the problem right away. Improper bleeding leaves air in the lines and (not sure about this one) can allow water to get in the lines - this was causing the brake fluid to BOIL, leading to the brake failures. Once the lines were PROPERLY bled I had no more problems. Tip: try to ID the brand of brake components you have on your car, you can then find out how many bleeder valves they actually have.

Yes, there are four up front and two in the rear. We started in the back, passenger side and then the rear driver side and then the front.
We used tubing connected to the bleeders and tubing was in canister of brake fluid. When we saw only fluid coming back we shut the valve.

It went to the floor because you had to compressed the piston to get it over the new pads and rotors. The brakes need to be pumped up after you replace pads in order for the pistons to come back in contact with the new pads and take up the gap. Pushing the pedal to the floor is never a good idea and a good way to ruin a master cylinder in older vehicles.

As far as the pulsation, have the rotors turned. Make sure the wheels are torqued to the proper spec when you are done (140 lb/ft). Pump up the pedal when you are done and you should have smooth braking.

sounds like you need to take it back to the mechanic and tell him this. then tell him to fix it correctly or pay for another shop to fix the problem. it seems that he is not getting it bleed correctly.

CHANGED ALL BRAKES NOW PEDAL GOES TO THE FLOOR CAN


If the pedal goes to the floor you may still have air in the system.I assume that the pedal was ok before you started and that you may have opened one or more of the bleed screws.
Check the fluid level at the master cylinder.It need to be at the proper level.
You will need to be positive that no air is in the system.If you are not familiar with brake bleeding do not attempt as you may cause more problems.
The use of a clear plastic hose that fits snugly over the bleed screws at the calipers and is immersed into a clear container may be helpfull to see if any air bubbles are present in the fluid.
A bleed kit may be obtained from an automotive supply store.

How do I bleed air from the brakes


Two persons are required: one to bleed and other to press brake pedal.
Remove wheel and hub of the side you want to bleed. You will find the bleed nut there. Open it a little until some oil flows out. Ask the other person to press brake pedal with steady pushing and withdrawing until he feels its tight while you slowly tighten the nut. Adjust tightness of pedal by trial. Don't forge to refill the brake fluid after bleeding all the brakes.

Do give my solution the highest rating if it solves your problem. Thank you for using fixya!

Brake pedal will go all the way to the floor


make sure brake fluid is full. then pump brakes for one minuite check the fluid to see if it went down or stayed full. if it went down then check the system for a leak . if it stays full then you will need a new mastercylender . i dont think you have a vacum problem cause this causes a verry stiff brake pedal not one that goes to the floor
